Tianjin ZhuoLiNeng(ZLN) Technology Co., Ltd. is a professional manufacturer of chemical processing systems. We have designed this hydrochloric acid equipment to give you a clear economic edge. The system accepts salt with a purity level of only NaCl > 89%, allowing you to use affordable industrial salt instead of expensive pure salt. This single feature can significantly reduce your annual raw material investment while keeping hydrochloric acid production stable and efficient.
To meet the needs of modern plants, ZLN integrates multiple functions into one compact package. The equipment combines salt reaction, hydrogen chloride absorption, acid concentration adjustment, and tail-gas purification. It is engineered for maximum gas-liquid contact, helping achieve high absorption efficiency and consistent acid quality. The modular structure also makes installation and capacity expansion easier for both new projects and revamping projects.
Key Design Advantages
Low salt purity requirement: Accepts salt with NaCl > 89%, cuts raw material cost and widens your supplier choices.
Robust corrosion-resistant construction: Process contact parts are made from PP, PVDF, FRP or titanium alloy, suitable for severe service.
Integrated modular design: Reaction, absorption and purification are combined to minimize floor space and installation complexity.
Energy-efficient operation: Heat recovery and counter-flow absorption improve HCl yield while lowering energy consumption.
Flexible capacity: The system can be customized from pilot scale to industrial scale to match your production target.
Automation optional: PLC-based control systems are available for precise monitoring of temperature, pressure and acid concentration.
Low maintenance: Simplified structural layout reduces maintainable parts and makes routine servicing faster.
Emission control: Integrated scrubbing and tail-gas treatment help minimize environmental impact.

From a technical perspective, the process begins by feeding salt and acid into the reactor, where hydrogen chloride gas is formed. The gas then moves to an absorption section, often a vertical packed tower or a combination of absorbers, where it is contacted with water or weak acid to generate hydrochloric acid at the desired concentration. ZLN carefully designs the gas flow path, packing materials, and liquid distributor to maximize mass transfer and minimize carryover. The closed-loop design helps contain fumes and protect the workplace environment.
The economic benefits of using low-purity salt are substantial. For operations that consume thousands of tons of salt per year, even a few percentage points of purity difference can translate into meaningful savings. With this ZLN system, the minimum requirement is only NaCl > 89%, so you can source from multiple suppliers, negotiate better pricing, and reduce reliance on scarce high-purity salt. The internal configuration prevents common impurities in the salt from interfering with the reaction process, ensuring a stable output.
Another important advantage is the low maintenance requirement. Hydrochloric acid equipment faces harsh corrosive environments that often lead to leaks and downtime. ZLN chooses advanced anti-corrosion materials and uses precision welding for key connections. The equipment structure is designed to reduce dead zones and facilitate cleaning, which extends service life and lowers operational expenditure.
For plant owners, the available automation options are flexible. If you need consistent product quality with minimal operator attention, a PLC-based control system can be added. This system can monitor reaction temperature, pressure, liquid level, and acid concentration in real time, and trigger alarms to protect the plant. If you prefer a simpler manual setup, the basic version includes convenient manual control valves and sight glasses for safe operation.
Safety is a priority in every design. The equipment can be equipped with pressure relief devices, emergency vent lines, and acid mist eliminators where necessary. For higher concentrations, corrosion-resistant ceramic or graphite components can be integrated. These choices are based on your specific working conditions, and our sales engineers will clarify them during the quotation stage.
Installation is not complicated. The modular skid-mounted design can be positioned on a prepared concrete foundation, and only water, electricity, and raw material connections are required. We provide clear installation drawings and can offer on-site guidance for the first startup. This minimizes engineering costs and helps you start production sooner.
The hydrochloric acid produced can be used for metal pickling and surface treatment, pH adjustment in water treatment, regeneration of ion exchange resins, synthesis of inorganic chlorides, textile processing, and many other industrial processes. By having your own HCL generation equipment, you can ensure supply security and avoid volatile market prices for transported acid.
ZLN supplies complete technical documentation, including P&ID diagrams, layout drawings, and installation instructions. Our engineers can also help you choose the right model based on local salt properties, utility conditions, and required acid concentration. Before shipment, every unit is tested to verify pressure tightness and basic performance, so you receive a reliable product.
As an certified company, Tianjin ZhuoLiNeng(ZLN) Technology Co., Ltd. is committed to quality management from raw material procurement to final inspection. We have served international customers in North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, and many other regions. Shipping from Tianjin port allows us to arrange fast export logistics. We value long-term cooperation and offer after-sales support, spare parts supply, and online troubleshooting. Contact us with your requirements, and we will provide a professional proposal with competitive pricing.
Frequently Asked Questions
Q: What is the minimum salt purity this hydrochloric acid equipment can handle?
A: The system is designed for salt with NaCl content higher than 89%. Lower purity salts may be acceptable after a feasibility test, depending on impurity levels and your target acid quality. Please contact us for evaluation.
Q: Can I use sea salt or lake salt instead of industrial salt?
A: Yes, the equipment can process different salt sources, including sea salt, lake salt, and industrial salt. The main requirement is that NaCl content should be above 89% and impurities should not create excessive foaming or poisoning. Customization is available.
Q: Is the equipment capacity customizable?
A: Yes, production capacity can be tailored from small pilot modules to large industrial lines. Our engineers will design the system based on your desired daily hydrochloric acid output and site conditions.
Q: What materials are used for corrosion protection?
A: Critical parts use PP, PVDF, FRP, and titanium alloys, which are widely recognized for excellent resistance to hydrochloric acid. Material grade selection depends on temperature, concentration, and pressure conditions.
Q: Does the equipment support automatic control?
A: Yes, a PLC-based automation system is optional. It can monitor parameters such as reaction temperature, pressure, liquid level, and acid concentration, allowing stable process control and data logging.
Q: What is the delivery time and are installation services available?
A: Delivery time varies with capacity and configuration. As a manufacturer, we provide on-site installation supervision, commissioning assistance, and operator training. Please state your project schedule in the inquiry.
Q: What after-sales support do you offer?
A: We offer technical advice, spare parts supply, and remote troubleshooting. Our after-sales team is located in Tianjin, and for major overseas projects we can arrange engineer visits or online video support.
Q: Do you have experience exporting to my country?
